My starting out recommendations would be to get a few good books, I like the Pete Bingham book because it was the first I started learning from, not sure if an updated or revised edition has been released... as it was about 25 years ago when I started. There are a few good books by Vivian Kistler on different aspects of framing, be careful of picking up books that are 'hobby' orientated, they're a waste of time, look for good books either in the Lion catalogue, the PFM bookshop, or from the Fine Art Trade Guild.

A few people mention offcuts, several times in the past I have had a clear out of moulding (offcuts and full lengths) which have gone to people starting out, I think this is a good way to get used to cutting frames on the morso, using different shaped mouldings, and joining them. You can use these frames up framing family photos or whatever, or sell them as ready made frames. I plan to post soon on the forum a load of moulding that I don't need that will be free... is a great way to get some practical experience with machinery for beginners.
Probably one of the best learning sources is right here on the forum, ask any question, even if is basic and people will gladly help advise.
